ETC misalignment has little impact as long as it does not obstruct the driver's vision or interfere with the normal detection by toll station equipment. Below are relevant details: 1. ETC: ETC is an Electronic Toll Collection system, where ETC-dedicated lanes are designed for vehicles equipped with ETC onboard units, utilizing electronic tolling methods. 2. Working Principle: The ETC system is currently the most advanced toll collection method for roads and bridges worldwide. It employs microwave-dedicated short-range communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at toll stations, leveraging computer networking technology for backend settlement processing with banks. This enables vehicles to pass through toll stations without stopping while paying the required tolls.

Is a Tire Scrapped if Punctured on the Sidewall?

Tire sidewall punctures can be repaired, depending on the following situations: 1. Tire sidewall damage: If the cords are not exposed and there is no air leakage, there is no safety issue, but it is best to repair the outer rubber protective layer to safeguard the cord layer. 2. Tire sidewall damage with exposed cords: If no more than three cords are broken and there is no air leakage, the outer rubber protective layer must still be repaired. 3. Tire sidewall damage with air leakage: If the puncture is within repairable limits, it can be fixed directly using a hot patch method. 4. Tire sidewall bulging: Cannot be repaired. Bulging occurs due to broken cords in the sidewall, so repair is not recommended—replacement is necessary. 5. Severe tire sidewall damage: If the puncture exceeds repairable limits or more than three cords are broken, repair is not advised, and the tire should be replaced immediately.

How to Distinguish Cylinders 1-6 in a Mercedes-Benz V6 Engine?

With the car's driving direction as the front, the three cylinders on the right side are cylinders 1, 2, and 3, while the three cylinders on the left side are cylinders 4, 5, and 6. Below is some relevant information about the Mercedes-Benz V6 engine: 1. Introduction One: This model of the V6 engine reduces fuel consumption by more than 20% compared to its predecessor models, with a corresponding reduction in CO2 emissions, while also enhancing power performance. These advantages primarily stem from Mercedes-Benz's latest generation of gasoline direct injection system, which operates through piezo injectors utilizing spray-guided combustion and high-pressure injection. 2. Introduction Two: The maximum output power is 225 kilowatts, with a peak torque of 370 Newton meters achievable between 3,500 and 5,250 revolutions per minute. Other factors contributing to reduced fuel consumption include the standard-equipped new intake and exhaust systems, controllable auxiliary units, intelligent generator management system, and consistent lightweight design principles.

Does driving through a waterlogged section affect the car?

Driving through a waterlogged section will not affect the car if the water depth does not exceed a certain level. Here is more relevant information: 1. Precautions for vehicle wading: Water entering the cylinder block does not have a lubricating effect. Restarting the engine can cause severe wear to engine pistons, cylinder blocks, etc., and in severe cases, even lead to engine failure. When driving to a waterlogged section, the driver should first decide whether to proceed based on the actual situation (water depth). 2. Hazards of deep wading: In terms of system damage to the vehicle. After the vehicle is soaked in water, there will inevitably be damage to the systems, such as the electrical system and powertrain. These are the core systems of the car, and even after repair, they will have a certain impact on usage.

Why is the urea fault light of China V diesel vehicle always on?

The urea fault light of China V diesel vehicle is always on due to lack of urea or loose sensor connection. Here is more relevant information: 1. The role of urea in vehicles: Vehicle urea is a diesel exhaust fluid that uses SCR (Selective Catalytic Reduction) technology to reduce nitrogen oxides in diesel vehicle exhaust. If the vehicle urea is missing or the SCR system malfunctions, the vehicle may exhibit symptoms such as weak acceleration, unresponsiveness to throttle, insufficient power, and inability to increase engine speed. 2. Specific solutions for urea faults: (1) If the vehicle shows symptoms of weak acceleration or white smoke from the exhaust pipe, professional equipment should be used to clean the urea crystallization in the exhaust pipe. (2) If the vehicle fault code indicates low urea pressure, urea should be replenished. (3) If the engine torque is limited and the speed cannot exceed 1800 rpm, the urea pump and sensor should be replaced.

Does Parking on Damp Ground Have Any Impact?

Erosion of the chassis: In humid environments, the oxidation rate of metal accelerates. The failure rate of chassis components will increase. Below are detailed explanations: 1. Interior moisture: Dampness and mold inside the car. Prolonged parking in underground garages makes the interior more prone to dampness and mold, especially in rainy southern regions, affecting the health of occupants. Iron components such as hinges and locks inside the doors and welded parts of the car body are also susceptible to rust and corrosion. It's crucial to ensure proper dehumidification to avoid hazards while driving. 2. Bacterial growth: Aging car paint. Due to temperature factors after summer rains and lack of sunlight in underground garages, the car interior is more likely to harbor various bacteria. Regular dehumidification and sterilization of the interior space are particularly important. Humidity also affects the car's paint, as it can easily lead to paint aging and discoloration. 3. Impact on circuits: Affects circuits and damages the engine. Long-term parking in damp locations can affect the car's components and wiring, especially the car's 'heart'—the engine. Without proper lubrication for extended periods, the engine's internal wiring can age, and parts can rust, leading to engine damage.
